A Bushfire Attack Level (BAL) Assessment is a statement of your Bushfire Attack Level (BAL) rating in the form of a certificate and report. The report gives detail about why you are that rating by the classification of vegetation in a 100 m radius around your development and measuring the separation distance from classified vegetation.
The heat flux that a structure would be exposed to in case of a bushfire is what denoted your Bushfire Attack Level (BAL) rating and is measured in kW/m2.
According to the Australian Standards AS 3959, bushfire intensity levels are divided into 6 Bushfire Attack Levels (BAL):
- BAL Low
- BAL 12.5
- BAL 19
- BAL 29
- BAL 40
